Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, and more specifically, to a heat treatment furnace with recyclable energy. Background Technology

[0002] Heat treatment furnaces are specialized industrial equipment used to heat, hold, and cool metallic materials to alter their internal structure and obtain desired properties. They are widely used in machinery manufacturing, automotive, aerospace, mold processing, and other fields. Heat treatment furnaces include annealing furnaces, quenching furnaces, tempering furnaces, and carburizing / nitriding furnaces. A heat treatment furnace typically consists of a furnace body structure, a heating system, a temperature control system, an atmosphere control system, and a cooling system.

[0003] In heat treatment furnace systems, waste heat recovery is a key technology for improving energy efficiency and reducing production costs. By recovering the high-temperature exhaust gas discharged from the furnace or the waste heat during the cooling process, fuel consumption can be significantly reduced.

[0004] Existing heat treatment furnaces typically discharge the heat treated gas directly during heat treatment operations. The discharged gas has a high temperature, resulting in energy waste during heat treatment. At the same time, the gas often contains impurities and particles, which affects the environmental protection of the production process and is not conducive to production operations.
